Brian J. d'Auriol, Scientific Visualization of Computation Spaces, Invited Colloquium talk, June 9, 2000, Computer Science Department, The University of Dayton, Dayton, Ohio, USA.
A new model, Geometric Representation of Programs (GRP) proposed by the speaker, defines a computation space as a group of computations (i.e., arbitrary statements of execution) that exist in a pre-defined Cartesian space. An iteration space is a specific (simple) example of a computation space that is defined by loop nest. A coordinate space is thus inherent in this representation. However, the computation spaces allowed in the GRP model are complicated by a number of factors. Given that visualization of programs in the GRP model is beneficial, it remains non-trivial to address the above questions. This talk presents the GRP model in terms of computational spaces and then explores how scientific visualization can be used to better understand the nature of the represented programs. Preliminary results obtained from AVS Express, a high-end scientific visualization commercial software, will be presented. |
